Can all iPhone 4s be unlocked using ultrasnow?

Can an iPhone 4S be unlocked using ultrasnow? Or do they need to be unlocked using gevey?

I'm talking about the 4S btw, not the 4.

No iphone 4s can be unlocked by ultrasnow.
and the gevey sim doesn't work on 5.1.1 or ios 6.
only the original carrier can unlock it

Sorry i haven't used the Ultrasnow and gevey sim to unlock it… I have used the Remote Unlock service to unlock it… It's best and safe to unlock it from network lock. Visit the site http://www.mobileunlocksolutions.com/apple-iphone-4s/rs1wp9/ get the Remote unlock service and unlock it from network lock easily.

No 4s can only be unlocked by the carrier.
